The little things between form and 'form'

After a long trip following my graduation from Metis, I went back proper into a routine this week. And today, I learned a great tidbit about how to render forms in Rails, very simple but it saves me a lot of time from now on.

I used to write the following:


<%= render 'form', form: form %>

For rendering a form partial. I couldn't just not put in the 'form: form' part because it would always say that form doesn't exist in the partial (in the form partial, there was - obviously, a form with it's associated fields designated as form such as form.text_area, and so on).

However, one of my colleagues pointed this out to me that I could just do:

<%= render form %>

The difference? By removing the quotations, Rails magic will immediately do the previous line I put up for me. That is very convenient, and actually solves a lot of my hassles (I've always wondered how people just write render form - and now I realize it's just the quotes!).
